Mozilla, the maker of Firefox, and Epic Games unveiled on Wednesday Unreal Engine 4 for the Web, software that could one day make it possible for the developers to create versions of their blockbuster games capable of running within browsers.

By porting Unreal Engine 4 for the Web, Mozilla said video games built using the engine will be able to easily be replicated for the Web, allowing gamers to play top-tier titles on their browsers without having to install anything on their computers.

Epic committed to porting Unreal Engine 4 to the Web last year, but this is the first time the game development company demonstrates a formal demo of the software. Video of Unreal Engine 4 for the Web can be seen above.

Vladimir Vukicevic, Mozilla's director of engineering, said that by porting Unreal Engine 4 for the Web, many developers of upcoming games will be able to easily create demos that can be shared with their fans using basic Web links.

This could prove to be a more effective form of marketing than simply letting users watch trailers of game footage, Vukicevic said.

“Instead of watching a game play video ... you might click a link and actually be thrown into the first five minutes of games,” Vukicevic said.

Mozilla, the nonprofit organization behind the popular Firefox Web browser, wants to know what exactly the National Security Agency has been monitoring -- and it has helped kicked off a campaign to find out.

In a rare demand that Fiat Chrysler Automobiles buy back as many as 193,000 flawed vehicles, the top U.S. traffic safety agency signaled a tougher stance on automakers that don't identify and quickly repair defects.
